biothesiometer

biothesiometer

A device for measuring the threshold of perception of vibration sense, which is of use when assessing peripheral neuropathies, as seen in diabetics.

biothesiometer

(bī″ō-thēz″ē-ŏm′ĕt-ĕr)
An instrument used to measure vibration perception.

biothesiometer

electrical device delivering a spectrum of vibration stimuli, where the greater vibration is represented by a higher scale value; a patient who cannot detect vibrations delivered at <23 V at the plantar skin is at risk of neuropathic injury

Vibration sensory testing was conducted using the Biothesiometer (Biomedical, Newbury, Ohio).
Therefore, this study was planned to evaluate the usefulness of the above modalities with the standard well validated screening method of measuring vibration perception threshold (VPT) with a biothesiometer in a population where foot care practices are scantly followed.
The biothesiometer probe, which vibrates at an amplitude proportional to the square of the applied voltage, was applied perpendicular to the test site with a constant and firm pressure.
We assessed sensory status using a biothesiometer (Bio-Medical Instrument Company, Newbury, Ohio) and by applying a Semmes-Weinstein 10 g monofilament (Touch-Test Sensory Evaluator, North Coast Medical, Inc, Morgan Hill, California) to the plantar surface of the foot.
Neuropathy was evaluated by history and of clinical examination using 10 g monofilament, vibration sense by biothesiometer (VPT at great toe >25 mV were considered significant) and ankle reflex (19).
DSEPs were found to be more sensitive for diagnosis of LSS when compared to the biothesiometer and the Semmes-Weinstein esthesiometer (64).
